I think at one point, I saw another reason why this wouldn't work, but maybe 
that reason doesn't exist anymore.  I'll have to think about this a bit more.

I also thought that:

ifneq ($(filter $(wildcard $(MAKEDIRLIST),$(MAKEDIRLIST))),)
  $(shell mkdir -p $(MAKEDIRLIST))
endif

would avoid $(shell)'ing if the directories are already there.

Thanks,
